I just did an installation of 2.2.7-RELEASE to a P2/400 HP Vectra. It
has an AZTEC sound card that shows up like:
Probing for devices on PCI bus 1:
Probing for PnP devices:
CSN 1 Vendor ID: AZT1008 [0x08105407] Serial 0xffffffff
...
sb0 at 0x220 irq 5 drq 1 on isa
sb0: <SoundBlaster Pro 3.1>
opl0 at 0x388 on isa
opl0: <Yamaha OPL-3 FM>
mpu0 at 0x330 irq 6 drq 0 on isa
mpu0: <MPU-401 MIDI Interface 0.0 >
It seems to be having some problems.. the mixer seems to work fine..
but using amp or mikmod or cating .wav files to /dev/dsp all give me
( loud ) static. I have tried to use Luigi's psm0 driver.. but that
is giving these errors :
Oct 29 11:05:01 daisy /kernel: timeout flushing dbuf_out.chan,
cnt 0xff00 flags 0x00000041
This happens when you run amp ( which again gives static ) which only
outputs for a brief moment. I have a friend here who is using the driver
successfully ( on a different card ) and he suggested configing with
the flags changed like so:
device pcm0 at isa? port? tty irq 5 drq 1 flags 0x15 vector pcmintr
Same problem reoccured.
I am not sure what is happening here.. I have tried manipulating the
BIOS parameters. I found that i have to tell it that the OS does
_not_ know about PnP in the BIOS for the card to show up at all. I am
fairly sure that nothing else is using either the IRQ or the address
for this card.. but it sure smells like an interrupt conflict.
Does anyone have any ideas?
